Exactly 80 years since an atomic bomb was used in war for the first time, thousands bowed their heads in prayer in Hiroshima on Wednesday, as the city’s mayor warned world leaders about the nuclear warheads that still exist today. The western Japanese city of Hiroshima was levelled on Aug. 6, 1945, when the United States dropped a uranium bomb nicknamed “Little Boy”, killing about 78,000 people instantly. Hiroshima was the headquarters of some military units and a major supply base during World War Two. US war planners calculated that the surrounding mountains would concentrate the force of the bomb and enhance its destructiveness.
